The reaction of N,N-dimethyl- or N,N-pentamethylene-formamide chlorides with n-butyl, cyclohexyl, and 2,4-xylyl isocyanides results in the formation of 1:2-adducts which are readily converted by water to N,N'-disubstituted α-(dialkylamino)malonamides. In the case of N,N-dimethylamide chlorides of acetic, propionic, and benzoic acids, the products are the corresponding N-substituted α-ketoamides resulting
N,N-二甲基或N,N-五亚甲基甲酰胺氯化物与正丁基,环己基和2,4-二甲苯基异氰酸酯的反应导致形成1:2加合物,这些加合物容易被水转化为N ,N′-二取代的α-(二烷基氨基)丙二酰胺。在乙酸,丙酸和苯甲酸的N,N-二甲基酰胺氯化物的情况下,产物是相应的N-取代的α-酮酰胺,其由1:1加合物的水解和连续的脱氨基作用而得。取决于两种反应物的组合,产率为10%至80%。
